Special Session (SS17): Modelling and Dynamic Performance of Inverter based Generation in Power System Transmission and Distribution Studies

Thursday, 22 June 2017
13:50 - 15:30

Theatre A

Organiser(s): Koji Yamashita, Central Research Institute of Electric Power Industry, Japan


This is a joined working group of CIGRE and CIRED. The JWG was created in 2013 with over 60 international experts from more than 20 countries and is expected to be completed in 2017. According to the questionnaire survey which was conducted in the JWG, still 30% of the system operators do not use any Inverter-Based Generators (IBGs) models for the dynamic power system studies. One of the reasons is more likely to be lack of model requirements of IBG for specific power system phenomena. The JWG has made an effort to provide answers to the following questions (i) What are the missing characteristics of Inverter-Based Generators (IBGs) compared to traditional synchronous generators?, (ii) Which functionality of IBGs needs to be modeled for each type of dynamic study? (iii) How can the necessary functionalities of IBGs be modeled properly in EMT and RMS-type simulations? (iv) How can IBGs be aggregated in MV/LV network? and (v) How can we validate IBG models? focusing on the Photovoltaic Generation as the IBG. The major outcomes and key findings related to RMS models will be maximally highlighted during the limited time.
